EDWARD E. ZILGLER, OF PHILADELPHIA PENNSYLVANIA.

HAND VIBBATOR.

Application filed July 19, 1921. Serial No. 485,906.

To all w/wm it may concern Be it known that I, Enwxnn E. ZIEGLER,

a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in, Hand Vibrators, of which the following is a specification.

This invention relates to massage apparatus and analogous devices for communicating vibratory treatments to various parts of the human body and it has more particular reference to that type or form of apparatus commonly designated hand-vibra tors that are employed by hairdressers for massaging the human face, such apparatus however being equally serviceable for treating the limbs or body of a patient locally for certain ailments or muscular atllictions and where it. is desirable to stimulate the blood circulation.

The primary object of my invention is to provide a hand-vibrator of the kind referred to in which the vibrations are efiectively directel to the fingertips instead of being partly distributed over the hand and arm of the user as has hitherto been prevalent with devices of the nature referred to.

Another object of my invention is topros vide a hand-vibrator having insulating cushions cmovably mounted thereunder whereby cleanliness is more effectively en sured whilst the device is resiliently supported in its entirety on the back of the operators hand.

A further object of this invention is the provision of a hand-vibrator characterized by a novel construction of vibrator-shaft and weight which ensures an effective end or axially directed vibratory thrust.

A still further object of my invention is to provide a lnind-vibrator which is simple in construction, cheap to manufacture, light in weight and by virtue of its pattern is much more comfortable and effective in use. as well as tl'ioroughly sanitary in every respect. V

With the foregoing and other objects in view as will become more apparent as this description proceeds. my invention consists essentially in the novel features of construe tion, combinations and arrangements of parts hereinafter more fully described and specifically defined by the appended claims.

In the further disclosure of the invention reference is to be had to the accompanying sheet of explanatory drawings constituting a part of this specification and in' which like characters of reference designate the same or corresponding parts in all the views.

Figure l is a side elevation of my improved vibrator as attached on the operators right-hand ready for use.

Figure 2 is a longitudinal sectional elevation of the hand-vibrator removed from the operators hand.

Figure 3 is a perspective view of the r0- tary weighted shaft; and,

Figure i is an enlarged plan view f the removable insulating cusiiioning means hereinafter more particularly referred to.

Referring more particularly to the views my improved hand-vibrator comprises a main or cylindric body portion 10 which is provided on its underside wit-h an integral depending longitudinal tongue or rib 11 of appropriate cr0ss-section to seat snugly in a correspondingly shaped groove or channel 12 provided for the purpose longitudinal of a standard or block 13 having a hollowed out base 14L including front and roar rest sections 15, 16 respectively, said main or cylindric body portion 10 being securely held in place on the block 13 by countersink screws 17 as will be clear-iv understood on an examination of the drawings. t is to be here remarked that the above mentioned manner of connecting the parts 10 and 13 effectively prevents any lateral displacement or movement of the former relative to the latter. Adapted for clamping attachment within the aforesaid base 141i is a fiber sheet 18 stiffened or braced by a metal strip 19 and said fiber sheet 18 has secured thereto as by lines of stitching 2O spaced rectangu lar blocks 21, 22 of appropriate insulating material such as soft rubber, the latter 22 being disposed under the rest section 15 and seating in use on the back of the operators hand 23 immediately in the rear oi" the: knuckle joints; composite rubber and leather strap 24 provided with eyeletsor spaced grommets 25 engageable on a stud 26 retaining the devicev securely in place. The former block 2'1v is disposed beneath the forward and downward inclined rest section 15 and seats upon the two middle fingers of the users hand between the knuckle and first finger joints an elastic or rubber hand 27 holding said block snugly on the aforementioned. fingers, and it will be readily seen that by this arrangement of parts the first ill) and little fingers are left perfectly free, whilst the forward parts of the second and third fingers are similarly free below the first finger joints; also thatpthevibrator in its entirety is supported in spaced relation to the hand over the knuckle joints thereof. The aforesaid fiber sheet 18 and metal strip 19 are clamped within the base 14 by a screw 28 as will be clearly seenby Figure 2 of the drawings, whilst ,I may attach the rubber blocks to the fiber sheet in any other appropriatemanner thatlends itselfto easy attachment and disconnection for purposes of cleaning or renewal.

Freely rotatable within the aforesaid cylindric body portion 10 is a rotatable weight 29 integral with a. shaft 30 journaled in the bearing 31 at the forward end ,of said cylindric, body 10, said shaft 30 being. adapted to be driven from the flexible shaft of an electric motor-not shown-.in any of the well known ways and as will be selfevident to those acquainted with theart to which my invention ,appertains. The-rotatable weight 29.js preferably made.as;illustrated most clearly by Figure 3, that is to say, it is formed withadisc-portion 32, a semi-segmentaldisczportionri-ll, and interveningvstepped portionsfi l, 35, the form of which is'segmental in cross-section hereas the latter is of relatively larger and crescent-shaped cross-section thus making vthe forward end of'said weight 29 comparatively heavierlthan the rearcportion and thereby ensuring what may be termed a forwardly directed eccentric thrust which wil ensure a constant non-variable vibration of the device when inaise. A stub or extension 36 of the shaft 30 is journaled in a bearing 37 integral ,with the removable cap ES-screw threaded into the end of the cylindric body portion 10.

By the use of the compound stepped weight 29 it will be readily seen that an even and forwardly directed vibration is obtained candrbyyirtue of the peculiar shape a considerable number of lvibrations per minute are ensured, said vibrations being mainly directed to the two-middle fingers of the operators hand and thereby rendering the device better adapted for local treatments.

In using my improved hand-vibrator the device is strappedion the hand by first passing the two inner vor middle fingers into the elastic band or loop 27 until the latter is positioned as shown in Figure 1, whereupon thecompositestrap is adjusted into position and hooked on to the stud 26, .the motor is then started whereupon it will be easily seen and understood that the palm of the hand, first and little fingers will be free to grasp or press: upon the part of the body to be treated whilst the inner fingers will transmit the vibrations directly thereto. Furthermore, it-will be observed that by the use of the soft rubber rest blocks or cushions 21, 22, no impediment is placed in the way that might tend to obstruct the proper blood circulation of the users hand whilst it will also benoted that no extra effort will be necessary on-the part of :the operator to'effect a proper vibratory masszwe.

Whilst I have shown vand described-the best form of the invention at present known to me it will be obvious that the same-is susceptible of minor detail changes and variations, and it is hereby intended to include all such reasonable modifications .or

other forms thereof .as fairly fall within the scope of the appended claims.

Having described my invention, what I claim as new and desire tosecure by Letters Patent is: V
